Passive Smoking Doesn't Cause Cancer -

The world's leading health organisation has
withheld from publication a study which shows that
not only might there be no link between passive
smoking and lung cancer but that it could even
have a protective effect. The astounding results
are set to throw wide open the debate on passive
smoking health risks.
The World Health Organisation, which commissioned
the 12-centre, seven-country European study has
failed to make the findings public, and has
instead produced only a summary of the results in
an internal report. Despite repeated approaches,
nobody at the WHO headquarters in Geneva would
comment on the findings last week.
The findings are certain to be an embarrassment to
the WHO, which has spent years and vast sums on
anti-smoking and anti-tobacco campaigns. The study
is one of the largest ever to look at the link
between passive smoking - inhaling other people's
smoke - and lung cancer, and had been eagerly
awaited by medical experts and campaigning groups.
Yet the scientists have found that there was no
statistical evidence that passive smoking caused
lung cancer.
The research compared 650 lung cancer patients
with 1,542 healthy people. It looked at people who
were married to smokers, worked with smokers, both
worked and were married to smokers, and those who
grew up with smokers. The results are consistent
with there being no additional risk for a person
living or working with a smoker and could be
consistent with passive smoke having a protective
effect against lung cancer.
The summary, seen by The Sunday Telegraph, also
states: "There was no association between lung
cancer risk and ETS exposure during childhood." A
spokesman for Action on Smoking and Health said
the findings "seem rather surprising given the
evidence from other major reviews on the subject
which have shown a clear association between
passive smoking and a number of diseases."
Dr Chris Proctor, head of science for BAT
Industries, the tobacco group, said the findings
had to be taken seriously. "If this study cannot
find any statistically valid risk you have to ask
if there can be any risk at all. "It confirms what
we and many other scientists have long believed,
that while smoking in public may be annoying to
some non-smokers, the science does not show that
being around a smoker is a lung-cancer risk."
